sys/fs/msdosfs msdosfs_lookup.c
Log:
Disable negative name caching for msdosfs to work around a bug.
Since the name cache is case-sensitive and msdosfs isn't,
creating a file 'foo' won't invalidate a negative entry for 'FOO'.
There are similar problems related to 8.3 filenames.
A better solution is to override VOP_LOOKUP with a method that
canonicalizes the name, then calls vfs_cache_lookup(). Unfortunately,
it's not quite that simple because vfs_cache_lookup() will call
msdosfs_lookup() on a cache miss, and msdosfs_lookup() needs a way to
get at the original component name.
